Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Every attachment-upload telemetry point now records which route was used

Under the hood
Useful1 Signal3
Telemetry

Attachment uploads now report which route they took on every outcome, success or failure.

What

Uploads report the lane they took (repl, env_brief_upload, env_ccr, env_byoc, sdk_hosted, sdk_hosted_disabled or none) on every outcome: missing token, too large, read failure, bad response, aborted, network error and success. The send events for briefs and user files report it too. Size limits and the provider and privacy refusals are unchanged.

Details
  • SDK-hosted results can also be flagged as having been rendered locally.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
